I have upgarded my kernel recently, and my wifi didn't work anymore. In fact, the firmware 3.0 doesn't make my wifi work, but the 2.4 yes see my dmesg with the version 3.0 : ACPI: PCI Interrupt 0000:03:01.1[B] -> GSI 18 (level, low) -> IRQ 19 ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[19] MMIO=[dfcfc800-dfcfcfff] Max Packet=[2048] IR/IT contexts=[4/4] ieee80211_crypt: registered algorithm 'NULL' ieee80211: 802.11 data/management/control stack, git-1.1.7 ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com> ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, git-1.0.8 ipw2200: Copyright(c) 2003-2005 Intel Corporation ACPI: PCI Interrupt 0000:03:03.0[A] -> GSI 17 (level, low) -> IRQ 18 ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection ipw2200: ipw-2.4-boot.fw load failed: Reason -2 ipw2200: Unable to load firmware: -2 ipw2200: failed to register network device ACPI: PCI interrupt for device 0000:03:03.0 disabled ipw2200: probe of 0000:03:03.0 failed with error -5 ieee1394: Host added: ID:BUS[0-00:1023] GUID[474fc0002fb65030] b44: eth0: Link is up at 100 Mbps, full duplex. b44: eth0: Flow control is off for TX and off for RX. with the version 2.4 : ieee80211_crypt: unregistered algorithm 'NULL' ieee80211_crypt: registered algorithm 'NULL' ieee80211: 802.11 data/management/control stack, git-1.1.7 ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com> ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, git-1.0.8 ipw2200: Copyright(c) 2003-2005 Intel Corporation ACPI: PCI Interrupt 0000:03:03.0[A] -> GSI 17 (level, low) -> IRQ 18 ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection ipw2200: Radio Frequency Kill Switch is On: Kill switch must be turned off for wireless networking to work. the tips comes from : http://forums.gentoo.org/viewtopic-t-453368-start-0-postdays-0-postorder-asc-highlight-ipw2200+ipw2+4boot+fw.html#3280870 i6000 hibou #

That's not a bug. The version of the ipw2200 driver included in linux-2.6.16 requires firmware version 2.4 (as seen in "ipw2200: ipw-2.4-boot.fw load failed: Reason -2"). Simply 'emerge =ipw2200-firmware-2.4'.
